Definitions

  • Port connector systems and methods as disclosed herein may be related to the field of medical fluid collection, disposal and other related methods, and more specifically, certain aspects may relate to medical waste fluid collection and/or disposal systems that utilize a rigid or semi-rigid canister for directly or indirectly storing various fluids and liquid waste; such canisters may include a flexible, semi-rigid or rigid liner for isolating fluid from the canister walls.
  • canisters and liners may include a rigid or semi-rigid lid provided with one or more openings or ports for communicating vacuum and/or waste fluid into and out of the interior of the canisters or liners.
  • Liquid waste may include secretions removed from a patient's body, which may include blood and other bodily fluids, irrigation liquids, or other fluids, such as suspended solids and various other particles.
  • a typical waste canister of the related art is a storage container in which negative pressure (also interchangeably referred to herein as “suction” or “vacuum”) is communicated so as to thereby create negative pressure inside the canister to draw or drain fluids and liquid waste from at or near a drainage or surgical site. Vapors, smoke, and particles and small solids suspended in liquids or gasses are also commonly drawn in the suction canister.
  • Gasses containing solids are typically filtered and evacuated from the canister, while other fluids and liquid waste are collected in the canister.
  • Canister systems may include a flexible, semi-rigid or rigid liner to isolate fluids and liquid waste from the canister walls.
  • Flexible liners are liners are frequently secured to the lid in an expanded or compacted state and are expanded to fit inside the canister walls when a seal is formed between the lid and the canister.
  • Collected waste fluid, including gasses may enter through a port in the lid or canister, typically referred to as an inlet port or a patient port.
  • a suction source may be communicated with the interior of the canister via a second port in the lid or canister, typically referred to as a vacuum port.
  • Gasses collected in the canister may be drawn by suction through a filter that may be positioned in the vacuum path between the collected fluid and the suction source.
  • Canisters or lids may have additional ports such as a tandem port for connecting additional canisters in a tandem configuration and a larger port for removing samples of collected fluid or adding solidifier or for evacuating the contents of the canister for disposal.
  • Fluid ports of the type used in suction canister systems typically include a cylindrical spout surrounding a particular opening in the lid and extending upward from an upper surface of the lid. An interior surface of the spout defines a conduit extending through the port, the conduit communicating the interior of the canister or liner with the exterior thereof.
  • the canister or the flexible or semi-flexible liner may be sealed, for example by capping or plugging the spouts of the various ports, and disposed of in a desired manner.
  • the canister may be reused with multiple new lid and/or liner assemblies. The canisters may be removed and discarded or sanitized periodically.
  • the abovementioned fluid collection systems and methods may include multiple canisters connected in a tandem configuration via one or more fluid conduits, such as medical suction tubing, to increase fluid and liquid waste capacity.
  • Canisters connected in tandem may be connected to a suction source in parallel such that each canister has an independent connection to the suction source.
  • the canisters may be connected to the suction source in series such that an end canister is connected directly to the suction source and suction is communicated from the suction source into the interior of the end canister, and to an upstream canister via a tandem connection that communicates the interior of the end canister with the interior of the upstream canister.
  • Multiple upstream canisters may be connected in this manner, and a first canister, being farthest upstream, may have a suction tube to collect fluids from a source and to deposit the fluids in the first canister.
  • a first canister being farthest upstream
  • fluid in the first canister passes into a second canister via a tandem tube connected between a tandem port of the first canister and an inlet port of the second canister.
  • each canister may include a shut-off valve upstream of the vacuum port to prevent fluids and other debris from entering and contaminating the vacuum system.
  • shut-off valves were typically mechanical in design such as a “floating ball” system that will close the vacuum port when liquid levels reach the height of the valve.
  • canister systems typically employ a porous plastic filter/valve that may be treated with a moisture-reactive powder, such as polysaccharide, polyacrylate or certain proteins, which serves to block the filter upon contact with aqueous liquid or aerosols, thus preventing potential contamination of equipment or spaces downstream of the filter.
  • moisture-reactive agents are dormant until the filter/valve is contacted by aqueous liquid or aerosol. As soon as the liquid starts to penetrate into the filter/valve, the liquid causes the powder to swell and form a colloidal gel. This cohesive gel structure serves to shut off the flow of fluids through the valve and into the vacuum system.
  • fluid may reflux or come out of one or more ports under certain circumstances.
  • vacuum is removed from the system, the pressure differential between atmosphere on the one hand and the cavity between the canister and the lining one the other, created by the vacuum between the canister and the liner, is removed. Removal of the vacuum allows the liner to collapse somewhat, due to liner elasticity, increasing the internal pressure on the fluid inside the liner. This increased pressure could cause fluid to be pushed out through the suction tube toward the patient or otherwise out of the canister, which may lead to contamination of personnel and other hazards.
  • the connector may include a connector that is suitable for connecting medical suction tubing with at least two different types of fluid ports in a medical fluid collection system.
  • the connector includes a generally cylindrical main body portion having an upper portion, a middle portion, and a lower portion.
  • the main body portion includes a cylindrical outer surface extending generally parallel to a central longitudinal axis of the body portion, and an inner surface defining a primary conduit extending through the connector.
  • At least one lateral closure wall extends radially outward from the main body portion.
  • At least one annular skirt wall extends longitudinally from the at least one lateral closure wall, including a first annular skirt wall that serves to receive an open mouth of a first fluid port having a relatively small diameter, e.g., a diameter of about 15 mm, and a second annular skirt wall that serves to receive an open mouth of a second fluid port having a relatively larger diameter, e.g., a diameter of about 25 mm.
  • an inner surface of the first annular skirt wall may be configured to engage an outer surface of a spout (also herein interchangeably referred as a port cone or port riser) of a first port in an interference fit such that the connector may be secured to the first port.
  • an inner surface of the second annular skirt wall may be configured to engage an outer surface of a spout of a second port.

  • the riser portion may include barbs, ribs, tabs, or other features for improving connection strength between the riser portion and various connected accessories.
  • the lower body portion may extend downward a greater distance than the skirt walls of the connector, thereby defining a lower mouth (i.e., opening) of the primary conduit that is positioned lower than the annular skirt walls.
  • the lower body portion may include a shoulder, step, ledge, ribs, tabs or other similar feature for gripping or engaging a port to provide secure or locking engagement of the connector with the port.
